The J7000 Break Check Valve can be easily fitted to any Jones wet barrel hydrant. If a hydrant is struck by a vehicle, the J7000 slowly closes automatically to minimize water hammer and protect infrastructure and property damage. This automatic shut off can reduce water loss by 90% or more. The J7000 emits a mist of water providing notification that an accident has occurred so crews can quickly get the hydrant back in service.
